It needs to have reverse, but it also needs to have the reverse type that allows you to have the stick at full forward and when it goes to the middle it stops the motor, and then when its pulled to minimum the motor has full speed the opposite way. I know that some esc has this thing that makes you break the motor and then push stick forward an inch and then back to enter reverse, such a regulator is not usable for my purpose.

This does what you're asking for, I recommended the 60A over the 45A as it should run cooler, allowing you to remove the fan, making it smaller. You can also remove the plastic casing if space is really critical.
